 Features we have recently released:
 
+- v0.9.50: Added support for self-hosted LLMs using [vLLM](https://blog.vllm.ai/2023/06/20/vllm.html).
 - v0.9.46: Released our plugin system, a German language plugin, early support for enterprise environments, and configuration plugins. Additionally, we added the Pandoc integration for future data processing and file generation.
 - v0.9.45: Added chat templates to AI Studio, allowing you to create and use a library of system prompts for your chats.
 - v0.9.44: Added PDF import to the text summarizer, translation, and legal check assistants, allowing you to import PDF files and use them as input for the assistants.

 - v0.9.26+: Added RAG for external data sources using our [ERI interface](https://mindworkai.org/#eri---external-retrieval-interface) as a preview feature.
 - v0.9.25: Added [xAI](https://x.ai/) as a new provider. xAI provides their Grok models for generating content.
 - v0.9.23: Added support for OpenAI `o` models (`o1`, `o1-mini`, `o3`, etc.); added also an [ERI](https://github.com/MindWorkAI/ERI) server coding assistant as a preview feature behind the RAG feature flag. Your own ERI server can be used to gain access to, e.g., your enterprise data from within AI Studio.
-- v0.9.22: Added options for preview features; added embedding provider configuration for RAG (preview) and writer mode (experimental preview).
